STI_UNUSED producing inconsistent results

[kylejacksonb]

Steps to Reproduce:
Using the Freetype-2.13.3 source code:
freetype-2.13.3.zip

I created the project by importing
\freetype-2.13.3\builds\windows\vc2010\freetype.vcxproj

Set the configuration to Debug|x64

Created a background CodeCheck configuration with only STI_UNUSED selected. I am now seeing inconsistent results. For reference, the inspection with 41 violations was performed with, "Start Work Process Serially," turned on.

Here are the violations flagged in 45 that weren't flagged in 31:

45diff31.csv

Here is the diff between 31 and 41. Red is items that were in 31, but not in 41. Green are items reported in 41, but not 31:

45diff31.csv

Here is the diff between 41 and 45. These 4 items are the same four items that showed in 31, but that didn't show up in 41:

Here are the entities that I believe to be false positives:
